Used By: The International Olympic Committee/World Anti-Doping Agency

The Tech: Performance-enhancing substances have been an issue in sports since testosterone was first synthesized in the 1940s. In order to combat the increasingly clever ways of concealing use, the IOC enlisted GlaxoSmithKline, a noted pharmaceutical company, to assist in new state-of-the-art lab tests that can measure more samples, and, if necessary, retroactively test for drugs not yet detectable.

The Catch: Despite the advancements, WADA estimates only 20% of cheats are being uncovered.

The Result: Albanian weightlifter Hysen Pulaku and Uzbekistan gymnast Luiza Galiulina were pegged as dopers, while judoka Nick Delpopolo came back with a positive test for marijuana.
